Summary: Fruit flies are economically important pests that can cause losses to fruits and vegetables. In this study, the toxicity and sublethal effects of a novel insecticide, broflanilide, were evaluated on four adult fruit fly species. The results showed that broflanilide was effective against certain species but had a higher toxicity to others. The findings emphasize the importance of considering species variation when using insecticides.

Summary: TxSnFELS is a common sublethal toxicity syndrome observed in ELS fish, characterized by reduced heart rate, edemas, and morphological abnormalities. This syndrome is mainly seen at high exposure concentrations and is considered a baseline, non-specific toxicity response, but can also occur at low doses through specific action.

Summary: The secondary metabolite, cyclosporin C, produced by Purpeocillium lilacinum, has lethal and sublethal effects on Plutella xylostella, a major vegetable pest, at both organismal and sub-organismal levels. It affects various physiological parameters, enzyme activities, and can serve as a potential insect control agent.

Summary: The study found that Proteus and matrine have higher toxicity to the western flower thrips, prolonging their development period and reducing fecundity, which inhibits population growth. In contrast, pyridalyl did not significantly affect the development and reproduction of the thrips.

Summary: This study aimed to determine the acute toxicity of chitosan oligosaccharide (COS) on the bird cherry-oat aphid Rhopalosiphum padi and the transgenerational effects of sublethal concentrations of COS on its biological characteristics. The results showed that COS had acute toxicity against R. padi after 48 hours of exposure, and a sublethal concentration of COS induced a decrease in adult longevity, adult prereproductive period, and fecundity in the first filial generation. Moreover, COS exposure significantly suppressed the population growth of R. padi F-1 generation while increasing the mean generation time.

Summary: This study determined the lethal concentration of emamectin benzoate (EMB) on the fall armyworm (FAW) and assessed its sublethal effects on parental and offspring generations. Sublethal concentrations of EMB significantly influenced the life cycle and reproduction characteristics of FAW. These findings have important implications for the rational use of FAW insecticides.

Summary: This study found that the effects of neonicotinoid insecticides applied using two spraying methods on the growth and development of silkworms were different. The quantitative spraying method was more stable and resulted in changes in economic indicators and detoxification enzymes in silkworms. DNA damage was also observed in silkworms treated with the insecticides. These results provide insights into the sublethal effects mechanism of insecticides on silkworms.

Summary: The sublethal effects of low concentration emamectin benzoate on the diamondback moth were investigated. The results showed that emamectin benzoate had an impact on the reproductive ability and development of the diamondback moth. The number of eggs laid by the adults increased, while the pupation rate, adult longevity, and ovariole length decreased in the treatment groups.

Summary: Dietary assessment reports and population surveillance programs have shown that chronic exposure to low levels of environmental cadmium adversely affects the health of both children and adults. This review assesses the current risk assessment model for cadmium and highlights alternative toxicity endpoints that are more relevant in deriving exposure limits. The review also discusses the association between low-dose cadmium exposure and reduced glomerular filtration rate and fertility, as well as the potential protective effects of selenium and zinc. Additionally, the review explores mitochondrial dysfunction as a potential mechanism underlying gonadal toxicities and infertility caused by cadmium.

Summary: Field development for optimizing the use patterns of spatial repellents is an ongoing research need. Results from investigating volatile pyrethroids in blends formulated into vegetation spray show that combination treatments have consistently higher adult mosquito reductions compared to single applications of metofluthrin or other existing products. Additionally, metofluthrin-containing treatments demonstrate significant decrease in nonviable mosquito eggs, total eggs, and adult mosquitoes, suggesting potential complex interactions for mosquito control in the field.

Summary: The study found that transgenic Cry1Ac + CpTI cotton did not have significant effects on aphid and parasitoid abundance, in-field parasitism rates, or food web structure. This work not only provides new insights into the ecological risk assessment of transgenic insecticidal crops, but also offers important data on the impact of nontarget arthropods in agro-ecosystems.

Summary: This study revealed a resurgence of the cosmopolitan bollworm Helicoverpa armigera in dynamic agro-landscapes following a reduction in Bt cotton area in North China Plain. The decrease in Bt cotton was correlated with higher levels of H. armigera population, resulting in increased yield loss and pesticide use frequency in non-Bt crops.

Summary: This study investigated the floral composition and predatory insects associated with the Gobi Desert in southern Xinjiang, China. Perennial flowering plants were found to be dominant species and could sustain diverse arthropod predators. Certain plant traits and herbivore abundance were related to natural enemy identity and abundance. This research provides valuable information for sustainable pest management and highlights the importance of non-crop habitats in supporting ecological resilience.

Summary: M. mediator prefers A. segetum-infested cotton plants over healthy plants, with the infested plants emitting significantly higher levels of compounds compared to healthy ones. These compounds play a crucial role in modulating the interactions between the pest herbivore and parasitoid, influencing parasitoid behavior. Enhancing biological control of A. segetum by M. mediator through the application of HIPVs may be possible.

Summary: Elevated temperature directly affects the population dynamics of the crop pest Aphis gossypii. Transcriptomic analysis reveals that a moderate temperature increase of 3 degrees Celsius can induce gene expression changes that help A. gossypii adapt to warmer temperatures. Hsp70 and CathB genes play essential roles in the adaptation of A. gossypii to high temperatures.

Summary: Intraguild predation between natural enemies can affect population dynamics and biological control effectiveness. This study investigated the feeding choices of Hippodamia variegata towards cotton aphid mummies and found no obvious preference for live aphids or mummies. The results showed that Aphis gossypii was the main prey source and medium of consumption for H. variegata. These findings are important for evaluating the pest control ability of H. variegata and strengthening biological control strategies.

Summary: Previous studies have shown that matrine is highly toxic to Aphis gossypii Glover, a cotton aphid, and has low toxicity to its natural enemy, Hippodamia variegata Goeze, a lady beetle. In this study, the safety of matrine to H. variegata was evaluated through investigations on its contact and stomach toxicity, effects on life-table parameters, predatory ability, flight ability, and cross-generational effects. The results indicate that matrine has no significant negative effects on the reproductive capacity, longevity, or predatory capacity of H. variegata, and can be safely used in the local integrated pest management strategy for controlling A. gossipii.
